Overview
The HMC998A is a GaAs MMIC pHEMT Distributed Power Amplifier die designed and manufactured by Analog Devices Inc. This amplifier operates over a wide frequency range from DC to 22 GHz, making it highly versatile for various high-frequency applications. It provides 14.5 dB of gain, 43 dBm output IP3, and +32.5 dBm of output power at 1 dB gain compression. The amplifier requires a quiescent current of 500 mA from a +15 V supply and exhibits a slightly positive gain slope, which is ideal for applications such as Electronic Warfare (EW), Electronic Countermeasures (ECM), Radar, and test equipment.
